T0 all 'whom't may concern.' 1

Be it lfnown that we, CHARLES E. OsMER and Josemi BARR Roacii, citizens of ,the

United States, residing at Beardstown, in the county of Cass and' State of Illinois, have invented certain new and useful linprovenients in Electrodes, of Which the following is a speciiicatioia,l reference being ,had to the accompanying drawings.

This .invention relate to certain 1rnprovev has relation more particularly to a device of this general character especially designed and adapted for general character which may be maintained in operative position Within the lamp Without the necessity of the auxiliary holder generally'employed in devices of this-character and whereby the electrode is rendered -abetter conductor of heat and thus reduce to 'a minimum the possibility of the copper fusing er burning.

-'.llie invention consists in the details of construction and in the combination and arrangement of the several parts of our improved electrode whereby certain importantl advantages are attained and the device is rendered simpler, lessexpensive and other- Wise more convenient and advantageous for .v use, all as will be hereinafter` more fully set forth. A i l The novel features of the invention will be carefullyv defined in the appended claims.

In order that our invention may be the better understood, we will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure l is a view in side elevation of an electrode constructed in accordance with. an embodiment of our invention, the 'same being shown in applied position, the coacting` clamping holder being indicated by dotted lines; Fig. 2 is anenlarged view in trout elevation of the electrode as disclosed in Fig. l; Fig. 3 is a sectional view takenl substantially on the line 3-3 of Fig. 2; and Fig. fi isa sectional view taken substantially on the line fl--4 of Fig. 2.

is disclosed in the accompanying drawings, 1 denotes a. clamp holder of conventional form having suitably engaged there with, the carbon 2 and positioned therebeneath is the electrode constructed in accordance with 'an embodiment of cui' present Specification of Letters Patent.

invention. As herein disclosed, our electrode 3 comprises an elongated member sub stantially circular in cross section and having its upper extremity'pointed, as at 4f, while its lower extremity is rounded or oftset, as indicated at 5, and terminates in the` greater dimensions than is commonly einployedv whereby such electrode is a better heat conductor and consequently preventing the same from fusing or burning.

From the foregoing" description, it is thought to be obvious that an electrode constructed in accordance with our invention is of an extremely simple and comparatively inexpensive naturev and is particularly Well adapted for use by reason of the convenience and facility with which the same may be employed vand by reason of the lengthened period of time the same may be used in comparison with devices of a similar character now generally used, audit will also be obvious that our invention is susceptible of some change and modification without niaterial departure. from the principles and spirit thereof and for this reason we do not wish to be understood as limiting ourselves to the precise arrangement and formation of the several parts herein shown in carrying out our invention in practice.

We claim: Y p

electrode comprising'- an elongated member having one extremity tapered and its opposite extremity ollset, such offset extremity being provided with a attened extension disposed in substantial parallelism with the body portion of the elongated member.`

2. As a new article of manufacture, an electrode comprising an elongated member having one extremity tapered and its op osite extremity oilset,such offset extremity being provided with Aa flattened extension disposed iii substantial parallelism with the bod-'y portion of the elongated member, such elongated member being substantially circular in cross section.
